The radio modem also encodes and packetizes data from a local computer or GPS receiver (or analog sense inputs). Successfully received data can be stored for later access, passed on to a local computer, or retransmitted to other sites, extending the range of a radio network. The digital data is then processed according to the modem's current mode and protocol. System diagram of site with radio modem As shown in the diagram, a radio modem/TNC extracts digital data from the analog (received RF audio) signal of a radio. So you can set up a simple, efficient radio network with K-NET™ or connect to the Internet with TCP/IP. With a Kantronics radio modem/TNC, your radio becomes a fully operational network node, able to communicate on virtually all popular protocols.
Additionally, the TNC (Terminal Node Controller) capabilities in Kantronics radio modems enable you to "plug into" radio networks.
